Intercostal muscles
-surround the lungs
-membrane that joins all the muscles as one
-such that the movement is the same
-pulls up the ribs
Sternum
-cartilage
-will not break
Trachea
-needs to be a tube in order to allow air to go in easily (lungs contain air already)
-is made of cartilage at some sections
-so that food in oesophagus (next to the trachea) won't affect the trachea
Pressure is inversely proportionate to volume
Therefore lungs need to expand (with the help of the intercostal muscles and diaphragm) to allow air to come in
We will still be able to have oxygen supply in areas of different pressure due to partial pressure (85% of oxygen will still be supplied to us)
More carbon dioxide dissolved in plasma - lower pH
Brain receptors will send message for more respiration when too much CO2
This will cause panting
Carbon monoxide has the same properties of oxygen; it will bind with haemoglobin
But it will form a greater bond in comparison to oxygen which will go away when pressure is lower
